Granuloma(redirected from actinic granuloma)
Also found in: Dictionary, Thesaurus, Medical.
a focal growth of inflammatory origin in the cells of young connective tissue in the form of a small node.
Granuloma develops in connection with various (most often infectious) processes (tuberculosis, syphilis, leprosy, brucellosis, tularemia, actinomycosis), with collagenic diseases (such as rheumatism), and at the sites of entry of foreign bodies. Certain granulomas have more specific names, such as the tubercle in tuberculosis and the gumma in syphilis.
